Be it knownthat I, HUMPHREY OLEARY, afcitizenof thefUnited States,residing in thecity and county of SanfFrancis'co and have invented newand which the following is a specification.

This invention relates to a hose coupling@ It is the object of thisinvention to provide a quick-action hose couplingwhich can be'4 easilyand quickly coupled. and uncoupled, and which is particularly adaptedfor use in attaching ahose to hydrants, fire-plugs, and the like, as iniire apparatus where aspeedy connection is desired, and in which the`use of turnable parts in eecting` the coupling A further` object istoprovide a hose coupling which is simple in construction, ei'it cient'and which canxbe manufactured at s`mallcost.` The invention comprisesdetails of construction which will be more fully explained' by referenceto the accompanying drawings,

in which- Figure 1 is a vertical section of the invention as applied toafire-plug.- Fig. 2 is a plan view. Fig. is a vertical section on theline X-X of Fig.. 2.

-In the drawings, A represents a fire-plug, the dischargeopening ofwhich consists of a horizontally extending, tubular member 2. i Theouter end ofthe tubular member 2 is formed with a conical outerface, asindicated at 3, which extends rearwardly of the member 2 and terminatesin an inwardlyl p extending, annular shoulder 4. The tubular member 2with its conical` head forms .the

male member of the coupling and maybe formed integralwith the nre-plugA, or it y may be mounted on other formsof conduits,

' such as pipes, hose, and the like.

Thefemale member lof the coupling conlsists of a tube 5," the innerendof which is "attached to a hose\B,or other conduit, in

any suitable manner. The means here shown for connectingthe tube 5 andthe hose B comprises a series of `annular serrations 6 Vformed on theinner periphery of thetube 5 adjacent to its inner end, which serrationsare causedto engage the end of the hose B by means of a crowding ring 7which is inserted in the end of the hose, afterthe latter,

has `been placed in the tube 5, in such a manner as to force the outerperiphery of with lthe perforations 9-9.

"qappiicgtion fiiediiiiy is, 1912.1v `sei-iai No. 709,715;` i

the hose intovl the `serrations. The inner, pe-

riphery of the outer end of the tiibeg'- is tapered tolconform to theconical end Sof ithe tubular `member`2 the tube 5 terminat- Ii ngv in anenlarged portion 8 which extends beyond 4the shoulder 4* when -"theyparts are oined together. Formed inthe upper side ofthe enlargedportion 8 of the tube 5 is a pair of rectangular perforations 9 9 whichVare elongated in the` direction ofthe length ofthe tube. Theseperforations are formed in such a position on the tube 5 as to be dislposed with their inner walls inl alinement with the outer periphery ofthe tubular member 2, rearward of the shoulderfl. Correspondingperforations 9-9 are formed onthe underside of the tube 5 in alinement Adetachable Ushaped wedge 10, the legs of which are slightly tapered, isprovided as a means for locking the member 2 and the tube y5` toapart adistance corresponding to that separating the perforations `9--9 so thatthey may be passed therethrough, as indicated in Figs. v2 and-3.` l

`In'assemblingthe. coupling, that is, to attach the tube` 5 to themember 2, the fornier is slipped over the latter,l as shown in Fig. l;the tapered face 3 of the member 2 contacting the beveled inner faceofthe tube 5. The legs of the'U-shaped wedge l0 are then` inserted inthe perforations 9 9 andpassed astride of the member 2 through theperforaticns99r; `the straightedges of the legs contacting the annularshoulder 4. The U-shapedwwedge is then driven downwardly, therebycausing the tube 5 to be drawn tight upon the `beveled head ofthe member2 to form a tight joint. It will be seen that a rapid coupling of theparts together can thus be easily and readily effected. As a means forfacilitating the removal of the U-shaped wedge 10, a screw-jack 1l isthreaded in the` transverse section thereof, thelower end of which isada ted to bear against the upper face of thetu e 5between theperforations 9-9. When it is desired to remove the U-shaped wedge 10 todisconnectvthe coupling, the screw is turned to l gether the legs ofthewedge 10 being spaced move downwardly in the wedge against the tube 5,so as to force the wedge in an up'- ward direction and so loosening itkthat it may be easily removed.

. Having thus described my invention, what l claim'- and desire tosecureby Letters Patent is f In a high pressure hose coupling in eombination7a pair of telescoping metal members, comprising an inner member, and anouter cylindrical member, the inner member being provided With a longconical surface,

an annular shoulder formed at the large end of the conical surface, theouter member being bored on its interior to form almetaltometal-contactwith the conical portion en the :inner member,.sa1d outermember belngyprovided With openings thel axes of which v intersect thecylindrical'portion of the said Copies of this patent may be obtainedforv ve cents each, by'addressing the A Cominissibner vof Iatems,

outer-member, 'anal a Ulshaped member hav- 15 detachablemetal-'tmetalWaterftight joint 2o between said members.
